Christian and Muslim terrorists

On the heels of Republican George W. Bush attacking Iraq based on a lie, the next Republican president, Donald Trump, has threatened to “totally destroy” North Korea. Add to that the Republicans’ denial of global warming, pulling us out of the Paris Agreement, and their determination to take away health care from millions, I am confused. Just what is the difference between right-wing Christian terrorists and right-wing Muslim terrorists, other than the methods they use to kill people?
